I'd like to propose a new winning criterion: Parallelize as much as possible. A challenge of this type is to give a code that involves parallelization. Let \$T\$ be the running time when run on a single processor. Due to Amdahl's law, as there are more and more processors to be run on, the overal...

This is a successor to a previous challenge. Input An integer \$1 \leq n \leq 5\$. Task Your code should produce all strings that satisfy the following properties: Your string should contain exactly two each of the first \$n\$ letters of the alphabet. It should not contain the same letter twice ...

Odd than even Your task is to find out how often you need to shuffle a given list with the following operation until you get back the original list. start with a list: (1 2 3 4 5 6 7 8 9) split it into the elements at odd and even indices (1 3 5 7 9) (2 4 6 8) concatenate these two list (1 3 5 7...

Walk by walls code-golf Challenge You just entered a room. Here's how it looks (you are the X): |\ /| | \/ | | X | | | |----| You challenge yourself to see if you can reach where you started by following the walls. You go right until you find a wall. Then you follow the next appropriate dir...

The product over a rectangle It is possible to generalize ranges of numbers to the Gaussian integers (complex numbers with integer real and imaginary part) by taking all numbers contained in the rectangle enclosed by the two ends of the range. So the range between two Gaussian integers a+bi and c...
